Prognostic biomarker intended for use in clinical trials. It will be used in conjunction with clinical high- risk for psychosis (CHR-P) or Attenuated Psychosis Syndrome (APS) diagnosis in young people aged 15- 35 years of age, to enrich for individuals most likely to progress to full psychosis and poor long-term functional outcomes.

To obtain formal feedback from the FDA regarding an individualized risk calculator for psychosis (IRC- P) as a prognostic biomarker. The IRC-P is proposed for use in future clinical trials and treatment studies to identify a subgroup of individuals meeting criteria for a CHR-P or APS diagnosis, that are most likely to progress to full psychosis and poor long-term functional outcomes (i.e., those most in need of treatment). The replicability of the IRC-P as a prognostic biomarker is being assessed by a multi-consortia international effort called HARMONY (Harmonization of At Risk Multisite Observational Networks for Youth). NAPLS is collaborating with the PRONIA (https://www.pronia.eu) and PSYSCAN (http://psyscan.eu) consortia studies based in Europe that have collected similar information on large cohorts of CHR-P individuals. The purpose of this submission is to solicit feedback from the FDA regarding the viability of the IRC-P as a prognostic biomarker for use in clinical trials, the current plan for conducting confirmatory studies, and next steps for testing the robustness of particular thresholds of predicted risk as cut-points for maximizing sensitivity and specificity of psychosis prediction. In addition, the applicant intends to explore re-analysis of prior clinical trial data on CHR-P samples incorporating individualized predicted risk as a factor in the statistical analysis, to determine whether treatment outcomes are moderated by level of predicted risk. If so, the resulting evidence may help to qualify the IRC-P for an expanded context of use in relation to treatment selection in a stepped care algorithm whereby the particular intervention (e.g., psychological, drug) is targeted/scaled to the individual’s level of predicted risk.
